The Lowdown
Alright, Rusty here, switching to feet and miles. Let’s look at Jaconé.
The main event is Wednesday the 15th in the morning. We’ve got a 6ft SSE swell, 10-second period, with ENE wind at 9 mph, offshore and clean. Wave energy is strong (715). This is the best the 16-day window has to offer. The water is about normal for the season.
Jaconé is a consistent, exposed spot that likes SE swell, so this SSE direction is a touch off, but the energy and wind make up for it. Crowds are sometimes a problem. The size is over 5ft, so it’s for intermediates, not beginners.
Thursday the 16th morning is still clean: 5ft SE swell, 10-second period, NE offshore wind at 9 mph. Energy is moderate (444). Good, but not as good as Wednesday.
Friday the 17th is smaller: 3ft SE swell, with a light NNE breeze at 6 mph. Energy drops to 395. Clean and fun for a smaller board.
Saturday the 18th morning has a 6ft ENE swell, but the period drops to 7 seconds – shorter, less powerful. Wind is light NNE, cross-offshore. Energy is moderate (480). Surfable, but a step down.
From Sunday the 19th onward, the surf goes flat for a long stretch. Swell sizes drop to 2ft to 3ft, with wave energy falling into the weak range (92, 78, 76, 67). The wind stays light and cross-offshore, so it’s clean but tiny.
There’s a small bump around Thursday the 24th with a 3ft SSW swell, 11-second period, but the wind is cross or cross-on – not worth it. By Sunday the 26th, a bigger S swell (4ft to 5ft, 14-second period) comes in, but with rain and a messy cross-onshore wind, it’s poor.
The end of the month, Monday the 28th morning, shows a 4ft S swell, 11-second period, with ENE offshore wind at 20 mph. Energy is moderate (438). Clean and rideable – a decent option for those waiting it out.
The best call is still Wednesday the 15th morning. After that, it’s a long gap of small, ordinary surf until the 28th.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
